But in this case, it seems to be correct. So, we, laymen, should update our concepts and throw away the idea that "0° is the lowest temperature."

- jessriedel 14y agoNo. If you don't know the abstract definition of temperature from statistical mechanics, you haven't learned anything from the headline "temp can actually be negative (properly defined)"
- cygx 14y agoBut 0K (notice there's no °) is the lowest temperature - it's just that it's also the hottest temperature, depending on which direction you're coming from. Temperature has a nice interpretation as average energy for classical systems, but in a sense thermodynamic β = 1/kT is the more 'natural' quantity that has a pole at T = 0, corresponding to infinite hotness or coldness respectively.
